Abstract
The use of thin-walled steel tanks in various industrial and structural fields has been increasing in recent years. One of the most important problems for tanks that are exposed to various effects throughout their lifetime is corrosion. There is a change in the cross-sectional properties of the tanks used for storage and containing chemicals with low pH due to corrosion. This deformation caused by corrosion also affects the strength of the tanks. In this study, four thin-walled steel tanks with the dimensions of 800x400x0.45 mm were filled with acid solution containing varying proportions of HCl (hydrochloric acid) and exposed to corrosion for 24 hours. The weight loss caused by corrosion was determined and the effect of this weight loss on the buckling behavior of the tanks was investigated. It was determined that as the filling rate of the tanks and the percentage of acid in the solution increased, the corrosion damage and thus the buckling damage increased. The number of buckling waves has increased in tanks with more corrosion damage.
